LG OLED 4k at 120hz, is it possible?

[WhereHere1]

Ok guys so I’m thinking about getting one of those LG OLED TVs that have g sync and 120hz.

I have a Gtx 1080, and even on modern GPUs they don’t have hdmi 2.


So how do I get it to run at 120hz when I only have hdmi 2.0b?

So there’s no point at all in getting a 4k 120hz tv yet then?

I was hoping there would be a DisplayPort to hdmi 2.1
